Abstract
Description
Technical Field
[0002] This invention relates to the field of orthopedic device technology, specifically to an adjustable orthopedic spinal correction device and method. Background Technology
[0003] In orthopedics, when the spine experiences abnormal physiological curvature, postural deviation, uneven stress, or vertebral misalignment, it can easily lead to neck, shoulder, and back pain, muscle strain, and decreased spinal stability. In severe cases, it may even develop into structural diseases such as scoliosis, kyphosis, or degenerative changes, thus requiring timely correction. To achieve effective adjustment of the spinal structure and stable support for related areas, spinal correction devices are usually used. These devices employ external traction, limiting support, and postural constraints to assist in spinal correction, promoting the gradual restoration of normal physiological curvature and biomechanical balance.
[0004] Currently, most common spinal correction devices use large-volume dedicated correction beds or one-piece molded correction chair structures. These devices are large in size and have a fixed structure, usually requiring dedicated space for use and are not convenient to move or store.
[0005] Therefore, it is necessary to design a spinal correction device that is easy to store and can be flexibly connected to different stools. Summary of the Invention
[0006] To address the aforementioned technical problems, this invention aims to provide an adjustable orthopedic spinal correction device and method. To solve these problems, this invention employs the following technical solution: An adjustable orthopedic spinal correction device includes two housings that are slidably connected. A traction mechanism is fixedly connected to the housing, and a cavity is opened in the housing. On the left side of the shell, a drive mechanism is provided inside the shell cavity. The drive mechanism includes a threaded rod, a movable seat, and a movable block. The movable block is slidably connected to the movable seat, and the movable seat is slidably connected to the inner wall of the shell cavity. The threaded rod is rotatably connected to the movable block. A power mechanism is provided inside the movable block. The power mechanism is connected to the threaded rod. A pull frame is fixedly connected to the movable seat. A movable block pushing mechanism is provided inside the shell cavity. The top wall of the shell cavity is connected to the top wall of the shell through a pulling channel. The pull frame extends into the pulling channel. On the right side of the shell, a movable plate is connected inside the shell cavity. A threaded hole is opened on the movable plate, and a threaded rod is threadedly connected to the inner wall of the threaded hole. Both housings are equipped with a switching clamping mechanism and a limiting support mechanism in their upper shell cavities.
[0007] Optionally, both ends of the threaded rod are fixedly connected to a driving bevel gear. The switching clamping mechanism includes a driven bevel gear, a bidirectional lead screw, and two clamping plates. The driven bevel gear is fixedly connected to the bidirectional lead screw, which is rotatably connected to the inner wall of the housing cavity. A lead screw nut is fixedly connected to the clamping plates. The lead screw nut and the bidirectional lead screw cooperate with each other, and the clamping plates extend to the outside of the housing.
[0008] Optionally, the limiting support mechanism includes a T-shaped strut, a limiting gear, a limiting insert, a permanent magnet plate, and a trigger permanent magnet strip. The T-shaped strut is fixed to the limiting gear, which is rotatably connected to the inner wall of the shell cavity. The limiting insert is fixed to the permanent magnet plate, which is slidably connected to the inner wall of the shell cavity. The trigger permanent magnet strip is slidably connected to the inner wall of the shell cavity and is connected to the inner wall of the shell cavity through an elastic element. The trigger permanent magnet strip extends to the outside of the shell, and the T-shaped strut extends to the outside of the shell.
[0009] Optionally, the movable block pushing mechanism includes a guide, a self-resetting elastic telescopic rod, a linkage rod, and an extension plate. The guide is fixed to the inner wall of the shell cavity, the self-resetting elastic telescopic rod is rotatably connected to the inner wall of the shell cavity, the linkage rod is fixed to the limiting insert rod, two push bars are fixed to the linkage rod, and two extension plates are fixed to the movable block.
[0010] Optionally, a damping slide rail one is fixedly connected to the inner wall of the shell cavity, the movable seat is slidably connected to the damping slide rail one, a damping slide rail two is fixedly connected to the movable seat, and the movable block is slidably connected to the damping slide rail two.
[0011] Optionally, the housing includes a horizontal section and a vertical section that are fixedly connected to each other.
[0012] Optionally, the guide is provided with two inclined surfaces.
[0013] Optionally, the self-resetting elastic telescopic rod is disposed between the two push bars.
[0014] Optionally, the self-resetting elastic telescopic rod is rotatably connected to the inner wall of the shell cavity via a rotating shaft.
[0015] An adjustable orthopedic spinal correction method, based on the aforementioned adjustable orthopedic spinal correction device, includes the following steps: Step 1: Turn on the power mechanism to rotate the threaded rod, thereby moving the movable plate to the right and causing the two shells to move away from each other. The distance between the vertical sections of the two shells is greater than the distance between the left and right walls of the seat plate. Step 2: Place the bottom wall of the horizontal section of the shell on the top wall of the seat, and have the user sit on the shell so that the two limiting support mechanisms abut against the sides of the body respectively. Step 3: Place the traction strap on the traction mechanism onto the corresponding position on the body; Step 4: The power mechanism reverses the threaded rod, bringing the two housings closer together. The two housings clamp and fix the seat plate, thus limiting the position of the limiting support mechanism. Step 5: Activate the two traction mechanisms, which will drive the traction belts on them to correct the human spine.
[0016] The present invention has the following beneficial effects: By setting two relatively sliding shell structures and cooperating with a threaded rod drive mechanism, the device can switch between the use state and the storage state. When not in use, the overall length can be shortened, thereby effectively reducing the space occupied. The detachable design between the device and the stool makes it easy to carry and store. The traction mechanism applies traction force to the human spine, and the limiting support mechanism supports and fixes the sides of the body, which improves the stability and safety during use while ensuring the corrective effect, thereby enhancing the overall corrective effect. The invention features a compact overall structure and high functional integration. Through simple manual operation and the cooperation of a power mechanism, it can achieve multiple functions such as shell adjustment and clamping mode switching. It not only enables quick clamping and connection of stools, but also reduces the number of electric drive components, which helps to reduce manufacturing costs and reduce the difficulty of later maintenance.

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.
[0024] like Figures 2-6 As shown, an adjustable orthopedic spinal correction device includes two housings 1, which are slidably connected. A traction mechanism 3 is fixedly connected to the housing 1, and a cavity 2 is opened on the housing 1; On the left shell 1, a drive mechanism is provided in the shell cavity 2. The drive mechanism includes a threaded rod 6, a movable seat 9, and a movable block 10. The movable block 10 is slidably connected to the movable seat 9, and the movable seat 9 is slidably connected to the inner wall of the shell cavity 2. The threaded rod 6 is rotatably connected to the movable block 10. A power mechanism is provided in the movable block 10. The power mechanism is connected to the threaded rod 6. A pull frame 4 is fixedly connected to the movable seat 9. A movable block pushing mechanism is provided in the shell cavity 2. The top wall of the shell cavity 2 is connected to the top wall of the shell 1 through a pull channel 5. The pull frame 4 extends into the pull channel 5. The power mechanism can be selected as an electric motor system, which includes an electric motor and several gears, and the rotation of the threaded rod 6 can be achieved by existing technology.
[0025] On the right shell 1, a movable plate 7 is connected inside the shell cavity 2. A threaded hole is opened on the movable plate 7, and a threaded rod 6 is threadedly connected to the inner wall of the threaded hole. Both housings 1 have a switching clamping mechanism and a limiting support mechanism inside the upper housing cavity 2.
[0026] The overall size of the device can be adjusted by the relative sliding of the two shells 1, so as to adapt to different stool widths and take into account storage needs. The traction mechanism 3 is used to apply traction force to the human body, and the shell cavity 2 is used to accommodate the internal functional mechanisms to achieve structural integration.
[0027] Based on the above scheme, optionally, both ends of the threaded rod 6 are fixedly connected to the driving bevel gear 8, and the switching clamping mechanism includes the driven bevel gear 11, the bidirectional lead screw 12 and two clamping plates 13. The driven bevel gear 11 is fixedly connected to the bidirectional lead screw 12, the bidirectional lead screw 12 is rotatably connected to the inner wall of the shell cavity 2, and the clamping plate 13 is fixedly connected to the lead screw nut. The lead screw nut and the bidirectional lead screw 12 cooperate, and the clamping plate 13 extends to the outside of the shell 1.
[0028] Through the meshing transmission of the active bevel gear 8 and the driven bevel gear 11, power is distributed to the bidirectional lead screw 12, thereby driving the two clamping plates 13 to move synchronously towards or away from each other, so as to achieve stable clamping of stools of different shapes.
[0029] Regarding the limiting support mechanism, the limiting support mechanism includes a T-shaped support rod 15, a limiting gear 16, a limiting insert rod 17, a permanent magnet plate 18, and a trigger permanent magnet strip 19. The T-shaped support rod 15 is fixed to the limiting gear 16, and the limiting gear 16 is rotatably connected to the inner wall of the cavity 2. The limiting insert rod 17 is fixed to the permanent magnet plate 18, and the permanent magnet plate 18 is slidably connected to the inner wall of the cavity 2. The trigger permanent magnet strip 19 is slidably connected to the inner wall of the cavity 2 and is connected to the inner wall of the cavity 2 through an elastic element 20. The trigger permanent magnet strip 19 extends to the outside of the housing 1, and the T-shaped support rod 15 extends to the outside of the housing 1.
[0030] By triggering the magnetic interaction between the permanent magnet strip 19 and the permanent magnet sheet 18, the limiting rod 17 is automatically inserted or disengaged, thereby locking or releasing the limiting gear 16, enabling the T-shaped support rod 15 to automatically complete the support locking or release of the human body, improving the ease of operation.
[0031] In a preferred embodiment of the present invention, the movable block pushing mechanism includes a guide 21, a self-resetting elastic telescopic rod 22, a linkage rod 23, and an extension plate 14. The guide 21 is fixed to the inner wall of the shell cavity 2, the self-resetting elastic telescopic rod 22 is rotatably connected to the inner wall of the shell cavity 2, the linkage rod 23 is fixed to the limiting insert rod 17, two push bars 24 are fixed to the linkage rod 23, and two extension plates 14 are fixed to the movable block 10.
[0032] To prevent the movable seat 9 and movable block 10 from sliding arbitrarily, a damping slide rail is fixedly connected to the inner wall of the cavity 2. The movable seat 9 is slidably connected to the damping slide rail, and a second damping slide rail is fixedly connected to the movable seat 9. The movable block 10 is slidably connected to the second damping slide rail. The first and second damping slide rails provide sliding resistance, preventing unnecessary positional displacement of the movable seat 9 and movable block 10. The resistance of the first and second damping slide rails can be set according to actual conditions to achieve the working process of this invention.
[0033] Note that the housing 1 includes a horizontal section and a vertical section fixedly connected to each other. The horizontal section is used to support the seat, and the vertical section is used to clamp and engage with the side wall of the stool.
[0034] In addition, the guide 21 is provided with two inclined surfaces. The inclined surface structure guides the movement trajectory of the self-resetting elastic telescopic rod 22, realizing automatic guidance switching under different working conditions.
[0035] Preferably, the self-resetting elastic telescopic rod 22 is disposed between the two push bars 24.
[0036] To achieve rotational guidance, the self-resetting elastic telescopic rod 22 is rotatably connected to the inner wall of the shell cavity 2 via a rotating shaft.
[0037] like Figure 7As shown, this is one of the optional configurations of the traction mechanism 3. The traction mechanism 2 consists of a power supply module, a power management module, a control module, a motor drive module, a feedback detection module, and a user input module. The power supply module provides electrical energy to the system, which is then regulated and protected by the power management module before supplying power to the control module and the motor drive module. The control module, as the core unit, receives start or stop signals and traction force adjustment signals from the user input module, and also receives detection signals from the tension sensor and displacement sensor in the feedback detection module. It then drives the motor drive module by outputting PWM and direction control signals. The motor drive module uses an H-bridge structure to control the forward and reverse rotation of the traction motor, thereby driving the traction actuator to generate mechanical output and achieve the traction effect on the human body.
[0038] like Figure 1 As shown, an adjustable orthopedic spinal correction method, based on the aforementioned adjustable orthopedic spinal correction device, includes the following steps: Step 1: Turn on the power mechanism to rotate the threaded rod 6, thereby moving the movable plate 7 to the right and causing the two housings 1 to move away from each other. The distance between the vertical sections of the two housings 1 is greater than the distance between the left and right walls of the seat plate. Step 2: Place the bottom wall of the horizontal section of shell 1 on the top wall of the seat board, and let the user sit on shell 1 so that the two limiting support mechanisms abut against the sides of the human body respectively. Step 3: Place the traction belt on the traction mechanism 3 onto the corresponding position on the human body; Step 4: The power mechanism reverses the threaded rod 6, bringing the two housings 1 closer together. The two housings 1 clamp and fix the seat plate, thus limiting the position of the limiting support mechanism. Step 5: Activate the two traction mechanisms 3. The traction mechanisms 3 drive the traction belts on them to correct the human spine.
[0039] Implementation process: In the initial state, the device is in a retracted state, with a shorter left and right length to reduce storage space. The driving bevel gear 8 and the driven bevel gear 11 are not meshed. The movable seat 9 is located at the upper limit position of the first damping slide rail, and the movable block 10 is located at the lower limit position of the second damping slide rail on the movable seat 9. The left end of the self-resetting elastic telescopic rod 22 abuts against the upper inclined surface on the guide 21, and the right end of the self-resetting elastic telescopic rod 22 abuts against the top wall of the lower extension plate 14. The limiting rod 17 is not inserted into the limiting gear 16.
[0040] When it is necessary to connect the device and the stool, perform the following steps: The power mechanism is activated to rotate the threaded rod 6, thereby moving the movable plate 7 to the right and disengaging the two housings 1 from each other, releasing them from their retracted state. The distance between the vertical sections of the two housings 1 is greater than the distance between the left and right walls of the seat, and the distance between the two clamps 13 is greater than the height of the seat. The bottom wall of the horizontal section of the housing 1 is placed on the top wall of the seat, and the user sits on the top wall of the horizontal section of the housing 1. The T-shaped support rod 15 is rotated so that the two T-shaped support rods 15 abut against the sides of the human body, and the traction belt on the traction mechanism 3 is placed on the corresponding position on the human body.
[0041] When the left and right walls of the stool seat are straight (e.g.) Figure 8 When (as shown): The control power mechanism rotates the threaded rod 6, causing the two housings 1 to move closer together. The vertical sections of the two housings 1 (with straight sidewalls) abut against the left and right walls of the seat, respectively, thus clamping the device onto the stool (the clamping piece 13 does not abut against the seat). The left and right walls of the stool seat will push the two trigger permanent magnet strips 19 to move against the elastic force of the elastic element 20. The trigger permanent magnet strips 19 move to below the permanent magnet piece 18. The magnetic repulsion of the trigger permanent magnet strips 19 causes the permanent magnet piece 18 and the limiting rod 17 to move upward. The limiting rod 17 inserts between the transmission teeth of the limiting gear 16, thereby limiting the limiting gear 16, so that the two T-shaped support rods 15 clamp the human body to facilitate subsequent spinal correction. The two traction mechanisms 3 are activated, and the traction mechanisms 3 drive the traction belts on them to correct the human spinal bones. When it is necessary to disconnect the device from the stool, simply move the two housings 1 away from each other. This will trigger the permanent magnet strip 19 to release its contact with the seat. Under the elastic force of the elastic element 20, the permanent magnet strip 19 will move backward and disengage from below the permanent magnet sheet 18. After losing the magnetic repulsion force of the permanent magnet strip 19, the permanent magnet sheet 18 will return to its original position under its own gravity. The T-shaped support rod 15 will then release its restriction on the limiting gear 16. The user can rotate the T-shaped support rod 15 to release its clamping and fixing effect on the body.
[0042] When the left and right walls of the stool seat are not straight (such as curved or bent surfaces as shown in 9): Pulling the pull frame 4 downwards via the pull channel 5 causes the movable seat 9, movable block 10, threaded rod 6, driving bevel gear 8, and movable plate 7 to move downwards (movable seat 9 and movable block 10 are relatively stationary). The driving bevel gear 8 and driven bevel gear 11 mesh, causing the self-resetting elastic telescopic rod 22 to rotate clockwise around the pivot. The right end of the self-resetting elastic telescopic rod 22 remains in contact with the lower extension plate 14, while the left end extends and remains in contact with the upper inclined surface on the guide 21. The control power mechanism rotates the threaded rod 6, causing the two housings 1 to move closer together. During this process, the two clamping pieces 13 on the bidirectional lead screw 12 will also move closer together.
[0043] The left and right walls of the stool seat push the two trigger permanent magnet strips 19 to overcome the elastic force of the elastic element 20. The trigger permanent magnet strips 19 move to below the permanent magnet plate 18. The magnetic repulsion of the trigger permanent magnet strips 19 causes the permanent magnet plate 18 and the limiting rod 17 to move upward. The limiting rod 17 inserts between the transmission teeth of the limiting gear 16, thereby limiting the limiting gear 16 and allowing the two T-shaped support rods 15 to clamp the human body for subsequent spinal correction. The upward movement of one of the limiting rods 17 will drive the linkage rod 23 to move upward. The upper push bar 24 pushes the self-resetting elastic telescopic rod 22 to rotate counterclockwise around the pivot. The left end of the self-resetting elastic telescopic rod 22 gradually shortens. When the linkage rod 23 moves down to the preset position, the left end of the self-resetting elastic telescopic rod 22 moves to the lower inclined surface on the guide 21. The left end of the self-resetting elastic telescopic rod 22 will extend under its own elastic force and move down along the lower inclined surface to the lower limit position. The right end of the self-resetting elastic telescopic rod 22 moves upward and pushes the upper extension plate 14. The moving block 10 moves upward relative to the moving seat 9. The moving seat 9 remains stationary due to the resistance of the damping slide rail, thus cutting off the power transmission between the driving bevel gear 8 and the driven bevel gear 11. The two driven bevel gears 11 continue to move closer together, and the two clamping plates 13 on the bidirectional lead screw 12 maintain their current height. The two left clamping plates 13 abut against the left wall of the seat plate, and the two right clamping plates 13 abut against the right wall of the seat plate. Due to the bent shape of the clamping plates 13, the contact area between the clamping plates 13 and the non-straight-faced left and right walls of the seat plate is increased, thereby increasing the clamping stability. The two traction mechanisms 3 are activated, and the traction mechanisms 3 drive the traction belts on them to correct the human spinal bones.
[0044] When it is necessary to disconnect the device from the stool, simply move the two housings 1 away from each other. This triggers the permanent magnet strip 19 to release its contact with the seat. Under the elastic force of the elastic element 20, the permanent magnet strip 19 displaces and moves away from below the permanent magnet plate 18. After losing the magnetic repulsion of the permanent magnet strip 19, the permanent magnet plate 18 returns to its original position under its own gravity. The T-shaped support rod 15 releases its restriction on the limiting gear 16. The user can rotate the T-shaped support rod 15 to release its clamping and fixing effect on the body. The limiting rod 17 then moves the linkage rod 23 downward. An upper push bar 24 pushes the self-resetting elastic telescopic rod 22 to rotate clockwise around the pivot. The left end of the self-resetting elastic telescopic rod 22 moves to the upper inclined plane and then moves along the upper inclined plane to the upper limit position. The right end of the self-resetting elastic telescopic rod 22 pushes the lower extension plate 14 down, causing the movable block 10 to move down relative to the movable seat 9 (the movable seat 9 remains stationary). The driving bevel gear 8 re-engages with the driven bevel gear 11, and the driven bevel gear 11 and the double-acting screw 12 reverse direction, causing the two clamping plates 13 to move away from each other and reset. If the left and right walls of the stool to be connected next are also not straight, there is no need to move the pull frame 4. If the left and right walls of the stool to be connected next are straight, move the pull frame 4 upward to disengage the driving bevel gear 8 and the driven bevel gear 11.
[0045] Beneficial effects of this invention: This invention achieves the switching between the use state and the storage state of the device by setting two relatively sliding shell structures 1 and cooperating with the threaded rod 6 driving mechanism. When not in use, the overall length can be shortened, thereby effectively reducing the space occupied. The detachable design of the stool makes it easy to carry and store.
[0046] By setting a switchable clamping mechanism and a movable block pushing mechanism, different clamping modes can be selected by moving the pull frame 4, thereby switching the clamping method. This allows the device to be adapted to stools with straight left and right walls of the seat, as well as stools with non-straight left and right walls of the seat, increasing the contact area of the clamping components and improving the stability of clamping and fixing.
[0047] By setting a limiting support mechanism, the magnetic action between the trigger permanent magnet strip 19 and the permanent magnet sheet 18 is used to realize the automatic insertion and disengagement of the limiting rod 17. This automatically locks the T-shaped support rod 15 when the device is connected to the stool, allowing the two T-shaped support rods 15 to clamp the human body for subsequent spinal correction. When the device is disconnected from the stool, the T-shaped support rod 15 is automatically unlocked, avoiding additional manual locking operations and improving the ease of operation.
[0048] By setting up structures such as the self-resetting elastic telescopic rod 22, the guide 21 and the linkage rod 23, the position of the movable block 10 can be automatically adjusted, and the power transmission can be automatically connected or disconnected in different clamping modes. The structure switching process does not require additional control, the linkage is strong, and the operation is simple.
[0049] This invention applies traction force to the human spine through the traction mechanism 3, and combines it with the limiting support mechanism to support and fix the sides of the human body. While ensuring the corrective effect, it improves the stability and safety during use, thereby enhancing the overall corrective effect.
[0050] The invention has a compact overall structure and high functional integration. Through simple manual operation and the cooperation of a power mechanism, it can realize multiple functions such as adjusting the housing 1 and switching the clamping mode. It not only realizes the quick clamping and connection of the stool, but also reduces the number of electric drive components, which helps to reduce manufacturing costs and reduce the difficulty of later maintenance.
